Although they have very similar scores, PerfectRec considers Lenovo Legion 7 to be very good for engineering and design, while the ASUS TUF Dash 15 is good.
The Lenovo Legion 7 outshines the ASUS TUF Dash 15 for engineering and design use largely because of its superior GPU, the Nvidia RTX 3070, and its higher-resolution, brighter screen, which are very important factors for such tasks. While both laptops offer 16GB of RAM and quality CPUs, the Legion 7's additional screen real estate and color accuracy are crucial for detailed design work; however, its heavier build and larger size make it less portable compared to the TUF Dash 15.

How the ASUS TUF Dash 15 and the Lenovo Legion 7 compare to other laptops
"The Asus TUF Dash F15 FX517ZR is a laptop with mobile RTX 3070 and acceptable battery life. The Asus TUF Dash F15 was made for high-performance applications like video editing, rendering, and gaming. The laptop can manage the latter in QHD resolution and at high to maximum settings. However, the focus isn't on maximum performance, but instead, it's about a compromise between performance and portability."
"The Lenovo Legion 7 is a fast 16-inch gamer with 165 Hz display. The new Lenovo Legion 7 is a very good gaming notebook that, despite its comparatively compact compact 16-inch case, does not have to do without the most powerful components. Thanks to good cooling, no compromises are made in terms of performance. Both the Core i9-12900HX and the GeForce RTX 3080 Ti perform at a very high level."
